1. Wyreless Access™ System (WAS)
1.1 Overview
Every access control system that uses Wyreless Access TM contains two different types of modules (Figure
1-1):
• at least one Wyreless Panel Interface Module (WPIM), and
• at least one Wyreless Access Point Module (WAPM)
Figure 1-1 – Wyreless Access System Block Diagram
The WPIM is wired to the access control panel and ideally is installed very close to the access control
panel. The WPIMs installation location is determined by the location of the WAPMs with which it will
communicate using RF.
The WAPM is installed at the access point where access will be controlled and/or monitored. Depending
on the application and which WAPM is used, some wiring at the access control point may be required.
Regardless of which WPIM or WAPM module is used, the communication link between the WPIM and
WAPM is always RF.
This manual describes the installation and operation of a Panel Interface Module-RS485-NexSentry
(PIM-485-16-TD-NXT), a WPIM.
